That Solaris works w/ a single CPU makes me wonder if it might be OS-7079 (still under review/testing so the fix hasn’t been integrated yet). The bug was introduced in 2009 (so it’s very possible Solaris still has this bug), but seems to have been hard enough to hit that it hasn’t been noticed until recently (the super micro 5028-TN4T seems able to trip it pretty reliably).
That’s why I’m curious if preventing the OS from attempting to start the other cores allows the system to boot (not a definitive test, but a suggestive one). > On Jul 22, 2018, at 2:56 AM, Michal Nowak <[email protected]> wrote: > >> On 07/22/18 12:03 AM, Robert Fisher wrote: >> > t seems that there were three BIOS updates since your original February >> > post regarding the motherboard.
